Does anyone encountered this error before and what would be the possible fix?
For some reason, I cannot join the Control Plane from Worker Node after setup.

Hi @katsloko,
When running labs on VirtualBox VMs the networking configuration of the VM instances plays the most important role in the successful bootstrapping of the cluster. I would recommend a single bridged adapter per VM to avoid other set up headaches.
Please watch the GCE and/or AWS EC2 instances provisioning videos from the first chapter, for tips on how to configure the networking of the two VM instances of the lab environment.
